Subject: [gentoo-user] b43-legacy and newer linux kernels?
Date: Fri, 13 Aug 2010 06:04:12
1 I have a laptop that has been running Linux Kernel 2.6.30 Gentoo-R8 (gentoo
2 sources, don't remember which version) for a while. It has a Broadcom 4306 Rev 2
3 wireless card that has been working well with that kernel. I extracted the
4 firmware from the broadcom-wl- blob a while ago using b43-fwcutter
5 011. I have to hard-code the network settings in /etc/conf.d/net for my home
6 network, but am able to use wpa_supplicant whenever I go elsewhere. (I think
7 it's my home wireless router that causes the issue; probably needs a firmware
8 upgrade.)
10 Any how, I recently upgraded to Linux Kernel 2.6.34 Gentoo-R7 (gentoo-sources
11 2.6.34-r1); again using the b43-legacy driver for the wireless. However, now I
12 can't keep a network connection up. I keep getting errors from the
13 /etc/init.d/net.wlan0 startup - namely: SIOCSIFFLAGS Unknown Error 132. I had to
14 reboot onto the older kernel to write this message and try to research the issue
15 a little.
17 From on-line, some sites suggest the following as a solution:
19 rmmod ath9k
20 rfkill block all
21 rfkill unblock all
22 modprobe ath9k
23 rfkill unblock all
24 however, rfkill seems to only be in testing for gentoo
25 (, and I'm using the
26 b43-legacy instead of the ath9k driver - okay, no problem there, just switch out
27 which driver is unloaded and reloaded. Haven't tried it yet as I have to reboot;
28 but even so - they are saying this has to be done on every reboot, and that's
29 not much of a solution.
31 Further, I can't seem to find a version of b43-fwcutter that will extract any of
32 the b43-legacy firmware - even the one I had successfully extracted (011, 012,
33 13).
35 Has anyone else seen this? Does anyone know if this gets resolved (or made
36 worse) by a newer kernel?
